为gridview中的每个数据设置不同的超链接

Question

I am try to add hyperlinks to the stockName in the gridview from the database. I manage to make the hyperlink to direct to a single page only. How can i add different url hyperlink for different stockname?

The url i wanna to add for the 1st stockname is gentingdisplay.aspx , 2nd is pangkordisplay.aspx , 3rd is langkawidisplay.aspx and so on.

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" 
        CellPadding="4" DataSourceID="SqlDataSource2" ForeColor="#333333" 
        GridLines="None">
        <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
        <Columns>
             <asp:BoundField DataField="StockID" HeaderText="Stock ID" 
                SortExpression="StockID" />
                <asp:HyperLinkField 
  DataNavigateUrlFields="StockName" 
  DataNavigateUrlFormatString="gentingdisplay.aspx?StockID=0" 
  HeaderText="Stock Name" 
  SortExpression="StockName" 
  DataTextField="StockName" />
            <asp:BoundField DataField="StockPrice" HeaderText="Stock Price" 
                SortExpression="StockPrice" />
            <asp:BoundField DataField="UnitAvailable" HeaderText="Unit Available" 
                SortExpression="UnitAvailable" />

Answer 1

As the documentation for DataNavigateUrlFields says, you can provide a comma-separated list of fields to use in the DataNavigateUrlFormatString .

So if I understand you correctly and you want the StockName to make up part of the hyperlink path and pass the StockID in the StockID querystring, you can use this in your HyperLinkField :

<asp:HyperLinkField 
  DataNavigateUrlFields="StockName,StockID" 
  DataNavigateUrlFormatString="{0}display.aspx?StockID={1}" 
  HeaderText="Stock Name" 
  SortExpression="StockName" 
  DataTextField="StockName" />

Here {0} maps to StockName and {1} maps to StockID , using the standard String.Format syntax.

Answer 2

You probably want

  <asp:HyperLinkField DataNavigateUrlFields="StockName" 
  DataNavigateUrlFormatString="{0}display.aspx" 
  HeaderText="Link" 
  SortExpression="StockName" 
  DataTextField="StockName" />

However, I think it may bad practice to organize your site with the pages designed in this manner - It may be hard to maintain.
